The oxygen isotope composition (δ¹⁸O_aragonite) of coral aragonite is dependent on two parameters, temperature and water oxygen isotopic composition. This tracer allows temperature reconstruction in tropical zones. Different published δ¹⁸O:temperature relationships show a slope derived from the regression δ¹⁸O against T(°C) which varies between -0.16 and -0.23 for Porites genus. This implies greater uncertainty for paleoclimatic reconstruction. The calibrations were generated differently. They were obtained from several colonies, collected in different locations or the formula was derived from the same coral head following seasonal variations of temperature. The relationships took into account of δ¹⁸O_Sw fluctuation or δ¹⁸O_Sw were estimated from salinity or were not considered. We show by using isotopic data from Weber and Raymond (1972) and assessing the δ¹⁸O_Sw value by two different methods that a thermodynamically significant formula is generated.
